> Yeah, masks and intentionally antagonizing police doesn't scream peaceful protest

They wear masks in case their political opponents take exception to their actions and hunt them down later and hurt their families.

(This seems like an extremely dubious justification to me, but I've been told on HN that this is the reason that ICE wear masks, so why wouldn't it apply here...?)

They wear masks to make it more difficult to arrest them (something which doesn't really apply to ICE).
